You mean Pull Request? It's not needed. My first problem was connected with using bullet without BT_NO_PROFILE. And jmonkeyengine-master-3.2c fixed it. After it I found another problem PhysicsCollisionEvent . It wasn't connected with any natives or jme source code. I just had to add physicsSpace.distributeEvents() in my own code after physics space update.

I don't use bulletAppState in that case. Actually, I found the solution after checking bulletAppState code.

My problem is just relevant for people who use PhysicsSpace manually (serverside in my case) without any AppStates. BulletAppState includes distributeEvents() in its update() method but PhysicsSpace isn't by its own.
